Equivalent & Substitute Parts for 4TPB330ML

Part Overview

The 4TPB330ML is a 330 µF molded tantalum polymer capacitor manufactured by Panasonic Electronic Components, rated for 4 V operation in the 2917 (7343 Metric) package. This component is part of the POSCAP™ TPB series and maintains Active product status. Tantalum polymer capacitors of this specification are used in applications requiring low ESR, compact form factors, and stable performance across industrial temperature ranges. Alternative equivalent parts may be required due to supply chain considerations, regional availability, or specific design requirements for lifetime ratings and moisture sensitivity specifications.

Key Parameters

Substitute Part Grouping Explanation

Equivalent substitution for the 4TPB330ML is determined by strict alignment of the following electrical and mechanical parameters:

• Capacitance value: 330 µF (±20% tolerance)
• Voltage rating: 4 V minimum
• ESR specification: 40 mOhm @ 100kHz
• Package designation: 2917 (7343 Metric)
• Mounting configuration: Surface Mount
• Operating temperature range: -55°C to 105°C minimum
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The substitute parts listed below meet all these core electrical and mechanical requirements, enabling direct functional replacement in circuit designs. Physical height variations and lifetime ratings represent secondary differentiators that do not affect primary substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All three components maintain Active product status and full regulatory compliance under ROHS3 and REACH standards. The 4TPB330ML, T520V337M004ATE040, and TCJY337M004R0040 are electrically and mechanically equivalent for circuit applications requiring 330 µF at 4 V with 40 mOhm ESR in the 2917 package.

The KEMET T520V337M004ATE040 and KYOCERA AVX TCJY337M004R0040 both specify 2000 Hrs @ 105°C lifetime ratings and Moisture Sensitivity Level 3 (168 Hours), providing defined reliability parameters for extended temperature operation. The Panasonic 4TPB330ML does not specify a lifetime rating in the provided data.

Physical height differences exist among the three parts: the 4TPB330ML seated height is 3.00mm, while the KEMET part measures 1.90mm and the KYOCERA AVX part measures 2.00mm. These variations may influence PCB layout and component clearance considerations in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can T520V337M004ATE040 or TCJY337M004R0040 be used as direct replacements for 4TPB330ML?

A: Yes. All three parts share identical electrical specifications (330 µF, 4 V, 40 mOhm ESR @ 100kHz) and the same 2917 (7343 Metric) package footprint. They are functionally equivalent for circuit operation.

Q: What is the significance of the height differences between these parts?

A: The 4TPB330ML has a maximum seated height of 3.00mm, while the KEMET part is 1.90mm and the KYOCERA AVX part is 2.00mm. These differences affect PCB layout clearance and component stacking. Verify that your design accommodates the specific height of the selected part.

Q: Do all three parts meet the same regulatory requirements?

A: Yes. All three components are ROHS3 Compliant and REACH Unaffected, meeting current environmental and hazardous substance regulations.

Q: What is the difference between the lifetime ratings?

A: The KEMET T520V337M004ATE040 and KYOCERA AVX TCJY337M004R0040 both specify 2000 Hrs @ 105°C. The Panasonic 4TPB330ML does not provide a lifetime specification in the available data. For applications requiring defined lifetime performance at elevated temperatures, the KEMET or KYOCERA AVX parts provide explicit reliability data.

Q: Are there moisture sensitivity considerations for these parts?

A: The KEMET T520V337M004ATE040 and KYOCERA AVX TCJY337M004R0040 both specify Moisture Sensitivity Level 3 (168 Hours). The Panasonic 4TPB330ML does not specify MSL in the provided data. MSL 3 indicates standard moisture handling requirements for surface mount assembly processes.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical interchangeability is confirmed. Physical height variations require verification against PCB layout constraints. Confirm that component placement and clearance specifications accommodate the selected part's dimensions.
